The Philips 8020 belongs to the MSX 1 family. In fact, it wasnt't built by Philips, but, as the Yashica MSX, built by Kyocera in Japan. The VG8020 comes in 3 different versions : 8020/00 are first PAL models, 8020/19 Secam models (black case) and 8020/20 PAL models with a more integrated motherboard.
There is another difference between the Secam and Pal models, one missing key. The Pal versions have one key at the right side of the right SHIFT key which is missing in the Secam version. It can be easily checked comparing pictures found here. The function of this key is for entering accents; specifically accent acute, accent grave, circumflex and tréma.
There's another vital difference between Secam and Pal models, the RF lead, which is missing in the Secam models.
Due to some differences in the chipset, the Philips VG-8020 was not always 100% compatible with other MSX-computers. Typing 'poke -1,170' before loading programs usually fixed the bug.
